ELECTRIC CANE.

SPECIFICATION forming part of Letters Patent No. 287,170, dated October213, 1883.

Application iilcd April 21, 1883.

T a/ZZ whom it may concern,.-

Be it known that we, ALFRED RoovERs and ALEXANDER RoovERs, both of thecity, county, and State of New York, have invented a new and usefulImprovement in Electric Canes, of which the following is a full, clear,and exact4 description.

Reference is to be had to the accompanying drawings, forming a part ofthis speciication, in which similar letters of reference indicatecorresponding parts in all the iigures.

Figurel is a side elevation of our improvement, the lower part of thecane being shown in section. Fig. 2 is a sectional elevation of theupper part of the improvement. Eig. 3 is a plan view of the upper end ofthe same, the cap being removed. Eig. 4 is a sectional plan view of thesame, taken through the line x x, Fig. 2. Fig. 5 is a plan view ofthesame, the part that contains the induction-coil being removed. Fig. Gisa sectional plan view ol' the same, taken through the line y y, Fig. 2.

The object of this invention is to connect a galvano-electric machinefor remedial purposes with a cane, so that the said machine can beconveniently carried.

The invention consists in an electric cane constructed with two tubularsections connected with each other and the lower section bynon-conducting couplings, and provided with a battery and aninduction-coil connected by a screw, a rod, and wires with the metallichead' and ferrule of the cane, as will be hereinafter fully described.

The cane is made in three parts or sections, A B C. The lowestsection,A, is the longest, and is made of wood or other suitablematerial. The short upper sections, B C, are tubular, and are made ofhard rubber or other suitable nonconducting material. In the upper endof the section A is formed a screw-hole to receive the smaller lowerpart of the coupling-plug D, the upperpart of which is screwed into thelower end of the middle section, B, and forms the bottom of the battery.i

E is the carbon, which is made in tubular form, and is secured inplaceby arod, F, which passes longitudinally through it and through thecoupling D. The rod F has a nut, G, screwed upon its lower end to restagainst the lower end of the coupling D, and has a nut,

(No modell) H, screwed upon its upper end, which rests against the upperend of the carbon E.

The Zinc I is in the form of a cylindrical cup of such a size as to iitloosely into the section B, and to receive within it the carbon E. Theupper end ofthe zinc I has ascrew-hole formed in it, and is screwed uponascrew formed upon the lower end of the coupling J, that connects thesections B C with each other, and that is screwed into the adjacent endsoi' the two sections. K is a screw which passes through the coupling J,and the lower end of which is perforated to receive and form an electriccontact with the upper end of the rod F. Through the couplingJ alsopasses ascrew, L, thelower end of which is in electric contact with thezinc I. The sections B C and the couplings D J are made of hard rubberor other nonconducting material, so as to serve also as insulators.Wvithin the upper section, C, is placed an ordinary induction-coil,which is kept in place by hard-rubber disks M N, secured to the sectionC by set-screws or other suitable means.

The primary circuit, when the switch O P is closed, passes from thebattery along .the screw L and wire Q, through the switch O P, along thewire R to the point S, along thehammer-spring T and screw U to theprimary coil V, and through the said coil V, the screw K, with which thesaid coil is in connection, and the rod E, to the battery. The passageof the current of electricity through the coil V causes the magnet XV toattract the hammer T, breaking the circuit, which destroys the magnetismof the magnet XV and allows the hammer T to spring back into contactwith the point S and again close the circuit, and so on continuously aslong as the switch O P is kept closed. The passage of the current ofelectricity through the coil V induces a eurrent of electricity in thesecondary coil X, which is connected at one end by a wire, Y, with themetallic cap Z, screwed upon the end of the section C, and serving as ahead to the cane. The other end of the secondary coil X is connected bythe screw K, rod F, and wire a., passing down through the section A,with the metallic ferrule b, placed upon the lower end of the cane, sothat when the head Z and ferrule b are grasped with the hands, or areIOO otherwise brought into contact with a human body or other conductor,a secondary circuit Will be established, and willpass through the saidbody or conductor.

We are aware that a cane electric apparatus is not broadly new; but

What We do claim as new and of our invention is- 1. An electric caneconstructed substantially as herein shown and described, and consistingof the sections A B C, the non-conducting couplings D J, the battery EI, the induction-coils V X, the magnet W, and the circuit-connections,as set forth.

2. In an electric cane, the upper sections, B C, made tubular, andconnected With each other and the lower section, A, by non-coned,"whereby the secondary current can be sent through the body of .apatient, as set forth.
